What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

Cofi ignition transformer TRK2-40VD is a compact high-voltage ignition transformer for gas and diesel burners. It operates from 220–240 V, 50–60 Hz and generates the high voltage needed for a spark at the ignition electrode. Dimensions are 85 mm x 60 mm x 37 mm. The housing is robust, and the ignition cable is silicone-insulated. It is made in Italy and fits Cofi TRK2 series.

Further details

Application	gas burners, diesel burners, heating boilers, heat generators, industrial heating equipment
Operating phase in burner sequence	energised only during ignition phase, de-energised after flame proved

Choosing and fitting

When replacing an ignition transformer, verify that the primary voltage and electrical connector match the burner control, and that the mounting fits the bracket. Ignition cables must be silicone-insulated to withstand high voltage and heat. Match the duty cycle rating to the burner’s ignition sequence; a transformer with too short a duty cycle may overheat if the control repeats ignition attempts.

Signs of failure

A cracked or hardened ignition cable can leak the spark to earth, mimicking a faulty transformer. A transformer with too short a duty cycle may overheat during repeated ignition attempts.
